Lego Grimlock from Rebrickable

My son and I have been using bins of Lego to build cool stuff off of Rebrickable. We found the instructions for this Grimlock, we pulled parts from our bins, local stores and bricklink. The creator did an amazing job designing it and it's G1 accurate, it does have robot mode and transforms but it is super fragile. After we put it all together I got annoyed with the parts falling away and we decided to keep it on a high shelf in dino mode. Overall it does look fantastic but I wouldn't want...
